STARTING AND OPERATING
The manu factu rer supports the use of reform ulated gaso-
line. Prop erly blend ed reform ulated gasoline will pro-
vid e excellent perform ance and durability of engine and
fuel system components.
Problem s that resu lt from using methanol/ gasoline
blend s are not the resp onsibility of the manu factu rer.
While MTBE is an oxygenate made from Methanol, it
does not have the negative effects of Methanol.
Gasoline/Oxygenate Blends
MMT In Gasoline
Some fuel suppliers blend unlead ed gasoline with oxy-
genates such as 10% ethanol, MTBE, and ETBE. Oxygen-
ates are requ ired in som e areas of the country during the
winter months to red uce carbon monoxid e emissions.
Fuels blend ed with these oxygenates may be used in
you r vehicle.
MMT is a manganese containing metallic additive that is
blend ed into som e gasoline to increase octane. Gasoline
blend ed with MMT provid es no perform ance advantage
beyond gasoline of the sam e octane nu mber withou t
MMT. Gasoline blend ed with MMT red uces spark plug
life and red uces emission system perform ance in som e
vehicles. The manu factu rer recom mend s that gasoline
withou t MMT be used in you r vehicle. The MMT content
of gasoline may not be ind icated on the gasoline pump,
therefore, you shou ld ask you r gasoline retailer whether
or not his/ her gasoline contains MMT.
CAUTIO N!
DO NOT use gasolin e contain ing Meth anol or E85
Ethanol. Use of these blen ds may resu lt in startin g
and driveab ility prob lem s and may damage critical
fuel system components.
